In 2006, while using her boyfriend's laptop, Surrey found a copy of a marriage license. Unsure of whose name was on it, she magnified the document to view it more closely. She could hardly believe what she was reading: The name on the certificate was that of her live-in boyfriend.

"After I found out my significant other of nine years had gotten married behind my back, I was devastated," Surrey said. "It took me a long time to trust a man again."

Surrey, a Jersey City resident, confronted her unfaithful partner with the license that showed he had recently exchanged vows. He told her his parents did not approve of their relationship because she was eight years his senior, so he married his wife to appease them. He had every intention of continuing the ruse. But Surrey wanted no part.

Surrey said she had no reason to be suspicious of him as they had lived together for years -- even after he married. Despite the disappointment, in November 2013, Surrey found herself in a new relationship -- but this one would be a business partnership. Her longtime friend Gary Spivak approached her with the idea for FidelityDating.com -- a dating website aimed at people who have been cheated on.

FidelityDating.com is their response to popular cheaters' websites such as AshleyMadison.com, whose motto is "Life is short. Have an affair."

"Having been a victim of infidelity, I thought it was a brilliant idea," said Surrey, 57. "I thought it was exactly what many people I had met over the years told me they were looking for."

It was what she had been looking for, too. In addition to running the website, Surrey is also among its 5,000 users.

But FidelityDating.com is not just for those done wrong.

"The idea of starting a website for those that might have been cheated on or betrayed -- but also for those looking to be in a faithful relationship, regardless of their past experiences -- really appealed to me," said Spivak, who has been married for 19 years.

Once a person signs up, he or she can search for a match based on proximity, sex and age. Like most matchmaking systems, the website pairs users based on their profile information: height, age, education, religion and other traits. The majority of users remain active for six to nine months. About 60 percent of its customers are women and 40 percent are men -- ranging in age from mid-20s to early 70s.

While the website is slowly attracting a younger crowd, Surrey said most users "have some life experience behind them."

"You definitely have a different attitude toward adultery and cheating as you become older," she said.

It appears the dishonest still outnumber the faithful: FidelityDating.com has a few thousand users compared to AshleyMadison.com, which claims to have 37 million members.

Surrey and Spivak plan to grow their website by continuing to raise funds for online advertising and through user referrals. The website is free to use now, but by January, will have a monthly membership fee of $29.95, with discounts for longtime members."We basically started a new niche dating site, so we don't have direct competitors," Spivak, 45, said. "If someone believes it's important to connect with someone who went through similar trauma of being cheated on or betrayed or are looking for a faithful partner, they would come to us."

Spivak, who lives in Paramus, worked as a financial adviser for nearly a decade. Surrey is an event producer and an event marketing specialist. The two leveraged their professional skills, experience and respective networks, and invested hundreds of hours -- and $2,000 dollars -- for Web hosting to launch FidelityDating.com in January.

Spivak and Surrey devote about 10 hours to their website each week and handle everything except for IT-related issues.

The website got a boost in May after it was endorsed on an episode of HLN's "The Dr. Drew Show"by Danine Manette, a fidelity expert and author of the best-selling self-help book "Ultimate Betrayal."

"There were various topics brought up on the show, but one segment was online dating and a viewer sent a question to Dr. Drew via Facebook: 'What is a good dating site to find love not hook ups?' " Spivak said.

To his and Surrey's delight and surprise, Manette recommended FidelityDating.com.

Rick Deane, of High Bridge, has been a member for nine months. The 48-year-old said he has tried other matchmaking websites, but found FidelityDating.com to be among the most straightforward.
